, MOTE-BOARD FOR COTTON-GINS.

Specification of Letters Patent.

Patented July 1, 1919.

Application filed October 19, 1917. Serial No. 197,448.

To all whom it may concern.

Be it known that I, JAMES L. WOOLDRIDGE, a citizen of the United States, residing at Decatur, in the county of Wise and State of Texas, have invented certain new and useful Improvements in Mote-Boardsfor Cotton- Gins; and I do hereby declare the following to be a full, clear, and exact description of the invention, such .as will enable. others skilled in the art to which it appertains to make and use'the same.

This invention relates to improvements in mote boards for cotton gins and the primary object of the invention is to provide a mote board construction adapted to cause all of the bolls, leaf, trash, dust and other foreign material to be thrown off by the centrifugal action of the saw cylinder dofling brush to be conducted away before the cotton lint is acted upon by the current of air which carries it through the gin conduit to the condenser, thereby preventing the air current from carrying the lighter impurities with the lint and consequently resulting in a cleaner cotton of ahigher value.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will 'be hereinafter more fully described, illustratedin the ac- In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, in which:

Figure 1 is 'a fragmentary section through a gin showing the improved mote board applied thereton p Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a fragmentary section showing a part of the mechanism for operating the mote board. I

Fig. 4 is a section on the line 44: of

Fig.3. 5

Fig. 5is an enlarged section through the upper end of the dirtpassage wal l, and

Fig. 6 is a detail perspective view of one of the-mote board supporting members Referring more particularly to the drawings, 1 designates an ordinary saw cylinder of a cotton gin, which saw cylinder is dofi'ed by the rotary brush 2. And 3 indicates the conduit which conveys the clean cotton to the condenser.

A pair of supporting members 4: are pivotally connected to the sides 5 of the gin easlng as shown at 6 and they include, the arm 7 and the substantially rectangular block portions 8 the upper edges of which are concavely curved as shown at 9 for forming a support for the mote board 10. The mote board 10 has its upper surface concavely out to conform to the curvature of the dotting brush 2 and it is disposed in spaced relation to' the dofling brush asclearly shown in Fig. 1 of the drawings, having its outermost ends overhanging the inner lower edge 11 of the conduit 3. The mote board 10 is attached to the members 4 inany suitable manner and lever 15 will rock the crank shaft 13 and consequently move the mote board 10 upon its pivot 6, for regulating the distance between the upper surface of the mote board and the rotary doffing brush 2. p

' l dust passage is positioned within the gin casing 5 directly beneath the engaging portion of the brushes 21 of the dofling brush 2 and the periphery of the saw 1. The passage 20 extends downwardly, and is formed by an inner wall 22 and an outer wall 23. The walls 22 and 23 are connected to the blocks 4 by suitable bolts 24: entering the mote board 10 and if it is sodesired spacing collars or sleeves may be mounted upon the bolt 24 for holding the walls 22 i and 23 in their proper spaced relation. The

walls 22 and 23 have their upper edges bent imwardly, as shown at 26, so as to slightly constrict or reduce the mouth of the dust passage 20. The dust passage 20 is prolighter impurities upwardly to i the con-1 denser, with the ginned cotton. By connecting the walls 22 and 23 totheblocks 4, these walls and consequently the dust pasthe mote board 10, by the rockingaction ,of

the crank shaft 12. The upper edge of the r inner wall 22 terminates at the upper end of the, mote board 10. By. the arrangement .of, themote board and walls 22 ,andu23 I of the dirt passage 20, it will bevseenthat all of themotes, leaf trash,.dust,and other 1mpurities will be conducted away ,by ,the dirt passage 20, prior toutheactionof thejair A current beforethe cotton, and thus a cleaner 7 grade ofcotton will be provided,;in that the said air current will be prevented from carrying the lighter timpurities upwardly through the conduit with ,the (Jotton andlby connectingthe, walls. 22,;and. 23 to thepivotallylmng members 4:, these wallsnia nbc adjusted with the adjustment ofthe mote boards so that the mouth-of the dust p assage will always be in the proper, receiv ng 1 position.

7 From the foregoing description 5 takenain connection a with, the accompanying draw- 35 ings the; advantages of construction, and the method of [operation of the improved mote boards for cotton ,gins will ;bereadily 5 apparent to those skilled inthe art. to which this invention appertainsandgwhile in the foregoing description, ,the principle offvthe i operation of this invention hasibeenigdescribed. together with various features of construction, it. is .to be understood that certain minor features of construction, combination and, arrangement .ofnparts mayabe altered to Suit practicalconditions provided .such alterations are comprehended within thescopeof what is claimed. 7 \Vhat is claimed is:
